Was someone with Joaquin when he called the paramedics when River died? The way she writes makes me think of that. Or is about someone who was close to Michelle or Heath in some way? Someone dating one of the Olsens?

It's not James Franco either.

River died at Johnny Depp's club, but I don't know if Depp was on the scene, and I'm not sure if he fits for other clues.

Gael Garcia Bernal

Well Gael Garcia Bernal costars with Michelle on the project she was filming in Sweden when she was told of Heaths death??

It's definitely Gael. I'm a bit shocked by this as I would NEVER have thought of him and certainly would never have guessed him.

Impish = he's 5'7" and certainly would qualify for being a hobbit
I've seen pictures of him protesting in the past, just can't remember where.
Very politically active, he was in the Che Guavera pic The Motorcycle Diaries and let's not forget last year's Babel.
He was a judge at last year's Berlin Film Festival (2007).

I'm now wondering if some of the recent changes in U.S. immigration policy are what caused the change in his behavior that Lainey mentioned ("last three months or so").

GGB: Politically aware quotes

Bernal's teenage years coincided with a tumultuous time in Mexican history. The country was emerging from what he labels 'an old tyrant democracy'.The Zapatista movement in Chiapas was rising up against the government. Street demonstrations were part of everyday life. Like many kids of his age, he was swept up by the energy and sheer excitement of the capital's mass support for the Zapatistas.

'That movement polarised the country, but it also united a lot of people,' Bernal recalls. 'We helped to stop the war. It felt that whatever we did would count. Something like a million and a half people demonstrated every day when the war started between the government and the guerrillas.

'I was very involved. I helped with sending food, writing and reading about the situation, and demonstrating about it on the marches. It was great. I was young, and it was fun. And I've got to say, I met my first girlfriend – my first real girlfriend – there as well. It was a great place to meet girls!'

Sex and politics. There's nothing po-faced about Bernal's political engagement. It's wrapped up in movies, fun, friendships, music, travel, theatre and family. There's something pleasing and bohemian about his world view. In Europe and North America, too few people believe that protest – let alone art – can make a difference. Bernal would get along fine in Paris circa '68.

Which helps explain why Bernal spent the past ten days at the WTO summit in Hong Kong. In Hollywood, political engagement more often than not means quick, loud gestures and red faces for all concerned. Bernal's commitment is more steady, more regular, more quiet. He attended the mass protests at the G8 summit in Edinburgh last year on the same weekend that Madonna and Elton et al performed very publicly at the Live 8 concert in Hyde Park. In Hong Kong, he sat diligently in meeting after meeting at the WTO summit, discussing ideas, presenting case studies, assisting grander delegates such as Mary Robinson, the ex-president of Ireland (or 'La Presidenta!' as Bernal calls her, laughing). Before travelling to Hong Kong, he spent time in the Chiapas region of Mexico, discovering for himself the effects that free trade is having on local maize and coffee producers.
